Xylosma pininsulare is a woody climber endemic to New Caledonia, only known from one locality on Ile des Pins (Pic N'Ga). It occurs in shrubland on ultramafic substrate up to 200 m asl. Its area of occupancy (AOO) and extent of occurrence (EOO) are both equal to 4 km². The main identified threat is habitat degradation by uncontrolled bushfires. This species is therefore listed as Critically Endangered (CR) under criteria B1ab(iii,v)+2ab(iii,v).

Geographical area


X. pininsulare is endemic to New Caledonia, where it is found only on Ile des Pins, at Pic N'Ga.

Population


Only one population (Pic N'Ga) has been identified, its size is unknown, but field observations indicate the species is rather abundant along the Mou river.

Habitat


X. pininsulare occurs in shrubland on ultramafic substrate up to 200 m asl.

Threats


The main identified threat is habitat degradation by uncontrolled bushfires.

Conservation


X. pininsulare is protected by legislation in Province Sud, but it doesn't occur in any protected areas. This species would benefit from ex-situ and in-situ emergency conservation actions. It is proposed that monitoring should occur to ensure the persistence of the known population. To ensure the preservation of a viable population, it is recommended to inform the DSCGR (emergency services) and local Management Committee on the presence of the species in the concerned area, and a protected area should be established in Pic N'Ga. It is recommended to look for this species in coastal areas (Araucaria forests, littoral vegetation on calcareous substrate).
